Have another random example:

The repository of (compiled) free software I habitually maintain at
every workplace I've ever been in so far has paths for all binaries
which contain the canonical name of the system they run on. Because
these paths are compiled into a number of those binaries, they can't
change safely without fairly large-scale recompilation.

(Thankfully, the filesystem supports symlinks, so I can work around
this: but it'll still be confusing for users who look inside the
appropriate directory and wonder why sparc-sun-solaris2.8 is a symlink
to sparc-sun-sunos5.8... pretty much the same `minor barrier' as was
originally referred to.)

Agreed.

It's not as though this change will be terrifically damaging, as long as
people replacing config.guess check that it still works as expected on
Solaris boxes...

... but that check may be unlikely to happen: it's not as though
config.guess triplets frequently change, or are *expected* to change.
